:MPRovnMnivT 1N HYDRANTS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern Beit known that we, JACOB FRICKER'andAMER- Ions WARDEN, both of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Fire-Hydrants; and we do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings making part of this speciication.

Our invention relates to that class Vof hydrants that are.,so, constructed that, after simply removing the ca p, the valve and valve-stem may be Withdrawn from the body or stock of thehydrant for repairs, without removing the body from the ground; and

' Our invention consists- First, in connection. with a square form ot valvest-eni, of a disk of metal, perforated with a square aperture to t the valve-rod, and secured to the stock of the hydrant in such a manner that, while it permits the valve to rise and fall in opening and closing, will, at the same time, prevent the rod from revolving.

It can also be twisted in place to permanently close the waste-vent of the plug at the bottom.

ment 'of main valve and waste-valve.

In the accompanying drawings- Figure 1 represents an external view of the firehyd'rant. i

Figure 2 is an axial section of the same.

Figure 3 is a plan of cap.

Figured is a plan of the disk-guide for the valvestem.

Figure 5 represents a plan of the shoe which .conneets with the water-supply.

A represents the iron body, in form as shown, with flange on top to attach the cap B, and aseries of lugs at the bottom to attach the shoe C; also a projecting ring, a, on inside, to receive the disk F.

IS represents the iron cap, with angeto attach to body, and is provided on the inside, near the top, with an inverted-angle seat and sleeve, in which revolves the composition-metal nut E.

C represents the shoe, provided with lugs for attachment to body, and socket to attach the connection-pipe from the street also, a raised seat for valve I), upon one side of which is arranged a small valve, operated by the main valve, when in the-act of seating, to empty the body, to prevent freezing in cold weather. Y

D represents the valve in three parts, the upper portion being a plain disk, the middle being also adisk of n India rubber, forming the valve, the lower portion bef ing a disk, with a series of projections downward for' guides, all being held together by the valve-rod passing 'through them, with nut upon upper and under the y, lower disk, both of" metal, the top disk having a lip projecting from one side to operate the waste-valve.4

E represents a brass metal nut, which, when rotated o'r revolved, raises and seats the valve, byan internal thread being provided to receive the valve-stem near the top. j

The upper end of the nut has a square formed on it, to receive a wrench, by which it is operated, and

below it is a thread to receive the nut H, and still be low itis an angle, formed to it the inverted angle in cap B, thereby forming a ground bearing for nut E and inverted seat of cap B. i F represents an iron disk, with a square hole through its center, by which the'valve-rod is guided in its vertical motion, the valve being simply raised from or lowered to its seat, but not rotated or revolved.

By revolving the disk one-quarter turn, it will rclieve the waste-valve from operation during the warm seasons. G represents the valve-stem of square wroughtiron, with thread cutnear top to receive nut E, and onbottom end the nuts to secure valve D.

Whatwe claim as new and of our invention, is- 1. In the described connection with the valve I), revolving nut E, and square valve-stem Gr, threaded at the end to fit the nut E, the plate F, having a square aperture to fit the rod G, operating as and for the purpose described.'

2. In combination with the stock A, having a main valve-seat at its lower end, of the construction dcscribed, and valve-stem G, the triple-disk valve I), the upper disk formed with a projecting lip, to operate the waste-valve by direct contact, in the mannerdescribed and for the purpose specified.
